Thousands of ransomware victims may finally get some long-awaited relief.
New Zealand-based security company Emsisoft has built a set of decryption tools for Stop, a family of ransomware that includes Djvu and Puma, which they say could help victims recover some of their files.
Stop is believed to be the most active ransomware in the world, accounting for more than half of all ransomware infections, according to figures from ID-Ransomware, a free site that helps identify infections.
Ransomware is one of the more common ways nowadays for some criminals to make money by infecting computers with malware that locks files using encryption.
Victims can unlock their files in exchange for a ransom demand — usually a few hundred dollars in cryptocurrency,.
Some security experts have been able to unlock some victims’ files without paying up by finding vulnerabilities in the code that powers the ransomware, allowing them in some cases reverse the encryption and return a victim’s files back to normal.
